CHANGE: GOP candidates rallying behind Trump.

Trump’s visit Tuesday to Nashville highlights the unmistakable trend: There is virtually no room between Trump and the Senate candidates hoping to maintain his Republican majority this year. And Republicans appear far more comfortable touting Trump’s leadership than Democrats do arguing against it.

Trump claimed that his sway drove Sen. Bob Corker from running for another term in Tennessee, and kept him out when he flirted with returning after all.

In his place is Rep. Marsha Blackburn, who faces only nominal opposition in August’s GOP primary. She is set to join nominees who have already emerged out of states including Indiana, Ohio, Pennsylvania, and West Virginia, by winning fights that centered on who the most staunch Trump loyalist would be.

It’s also telling that while Trump is primed to attack the likely Democratic candidate in Tennessee, Phil Bredesen, Bredesen is already on TV promising to “separate the message from the messenger.”

“Look, I’m not running against Donald Trump,” Bredesen said in a recent campaign ad.

I’d still feel better if the GOP Congress were busier fulfilling its promises, but this looks less and less like a blue wave.
