Washington (CNN)A number of high-profile Republicans, fearful of a potential melee in Cleveland this summer, are considering skipping the Republican National Convention and campaigning back home instead.

With the presidential campaign hitting a fever pitch and Donald Trump warning about riots if he's denied the nomination, some House and Senate Republicans tell CNN that it makes more sense to spend time with voters back home rather than be associated with the drama engulfing their party.

But even some leading party stalwarts are planning to skip the convention.

Asked Tuesday if he'd attend the convention, former Florida Gov. Jeb Bush told CNN: "No."

"Unlikely," GOP Sen. Kelly Ayotte said when asked if she'd be in Cleveland in the midst of her tough bid for a second term. "I've got a lot of work to do in New Hampshire, I have my own re-election and I'm going to be focusing on my voters in New Hampshire."

The decision underscores the dilemma confronting Republicans in being tied too closely to the top of the ticket -- particularly incumbents from swing states worried that Trump's divisive candidacy and Ted Cruz's rigid brand of conservatism will doom their chances at keeping power in both chambers of Congress.

If you think Donald Trump’s campaign rallies are violent what’s happening online is spiraling out of control too. Trump supporters have turned their rage to the chair of the Colorado Republican Party as well as Republican delegates in Indiana.

Colorado GOP Chair Steve House posted on his Facebook page that he has received over 3,000 calls to his home, some of which were death threats. Trump supporters evidently blame House, not Colorado law, for running a caucus instead of a primary and have posted House’s personal information online. Trump has had more success in primary states, so the fans are turning their anger to party officials.

In Indiana, Republican delegates are incurring the wrath of Trump supporters after some of them expressed reservations about Trump, according to the IndyStar. Delegates received threatening emails warning that they are being watched and implied they could be targeted. Some of the Trump supporters even sent intimidating notes to the families of the delegates as well.

“You sorry (expletive)!” GOP delegate Craig Dunn said he got via email. “I hope the worst for you and yours!”

“If no candidate has a majority on the first ballot, I believe that you should only choose from a person who has actually participated in the primary,” Ryan said. “Count me out.”

“I simply believe that if you want to be the nominee for our party, to be the president, you should actually run for it,” he said. “I chose not to do this, therefore, I should not be considered. Period. End of story.”

But the Wisconsin Republican was less definitive on what will happen in July during the GOP convention. The speaker, who is chairman of the convention, seemed to accept that a contested convention was a real possibility, and that the nomination wouldn’t just be handed over to the person who is closest to a majority of delegates.
