"Trying to count the ways I hate @timkaine. Drawing a blank," Flake tweeted, adding that Kaine was a "good friend." 

Clinton's official account retweeted Flake's post.

Pennsylvania Sen. Pat Toomey, another vulnerable Republican, also sent out a statement lauding Kaine.

The Republican National Committee quickly blasted the ticket, although Chairman Reince Priebus didn't aim any attacks specifically at Kaine other than to say he "holds positions that she’s spent the entire primary trying to get to the left of."

"A Clinton-Kaine administration will push our country further down the path President Obama has led us on and that has made us less safe, less prosperous, and less free. More taxes, more debt, more government and more leading from behind on the global stage will not deliver the turnaround our country desperately needs. Americans have had enough of the failed Democrat status quo," Priebus said.
