If Train H is traveling from New York to California at 50 miles an hour, and Train B is on a parallel track moving at 48 miles an hour, basic math tells you which train arrives in first place.

Last night, Hillary Clinton added at least 135 delegates to her presidential bid, while Bernie Sanders picked up at least 104. Not a big difference, but the state-by-state trend matters. Toss in superdelegates, and the Democratic side of the race for the White House could soon be over, according to an Associated Press count:

Clinton added 33 new endorsements over the past month, according to an Associated Press survey, expanding her overwhelming support among the party officials who can back any candidate, despite Sanders' recent string of victories in Wisconsin and the West. Sanders picked up seven.

The AP count, including New York:

— Based on primaries and caucuses: Clinton leads, 1,428 to 1,151.

— Including superdelegates: 1,930 to 1,189.

Sanders must win 73 percent of the remaining delegates and uncommitted superdelegates to get the nomination. It takes 2,383 to win.

The Republican chair of the suburban Atlanta district where spurned Donald Trump supporters stormed out with Old Glory in tow said he and his family have been targeted by threats from the billionaire's supporters.

Jason Thompson, who chaired the 7th District GOP meeting in Gwinnett, said he's been called "inexcusable names" and been accused of disenfranchising voters after Ted Cruz allies blocked Debbie Dooley from becoming a delegate for Trump. That gathering was one of 14 around the state where Trump forces struggled, but it was the only where outraged Trump supporters marched out of the room with an American flag.

Jason Thompson's wife, longtime GOP activist Julianne Thompson, is the national co-chair of the group Women for Cruz. But Jason Thompson said in a Facebook post that he took "fairness and the rules into account, so much so that as to avoid anything that could be construed as unfair to any campaign I even withdrew my name for consideration" as a delegate.

Let me also say that I have been involved in the Republican Party since college. My children have grown-up in the 7th District, and the members of our District I consider to be extended members of my family. And members of my District have also been personally threatened. There is no excuse for this and it will not be tolerated.

I will conclude by saying that we have an election that is ongoing and our ultimate goal should be to defeat the left in November. We cannot do that divided.

If you want to be part of the problem let me be very clear - threats, intimidation, and Saul Alinksy-style thuggery will not be met with understanding. If you want to be part of the solution, then we must find a way to work together, and I will do everything I can to facilitate such."

The 9th District congressional race continues to get more heated with each passing day, and the newest radio ad from incumbent Doug Collins pulls no punches in its takedown of Paul Broun, the former Athens congressman who is one of four Republicans challenging the two-term incumbent in the May 24 primary.

The one-minute spot, which is being aired on a dozen stations across the congressional district today, is a compilation of headlines raising ethics questions about Broun and his former staffers (it includes items penned by the Atlanta Journal-Constitution).

Listen to the spot here:

Here's a partial transcript (the links are ours):

"The Atlanta Constitution reports the U.S. Justice Department announced that former Congressman Paul Broun's former chief of staff has been indicted in connection with misusing taxpayer money to finance campaign activities.

"...Former Congressman Paul Broun's most recent troubles began when his former speech coach copped a guilty plea related to the ethics case against then-Congressman Broun."
