A new Hillary Clinton fundraising email wants donations to help handle the "wild ride" that awaits if her Republican opponent winds up being businessman Donald Trump.

Deputy Communications Director Christina Reynolds assailed Trump's remarks Tuesday evening after his sweep of five primary states where he said Clinton's only asset was "the woman's card." Trump suggested Clinton would not even reach five percent of the vote if she were a man, and Reynolds said Trump's "dangerous rhetoric" meant Clinton needed to be as prepared as possible:

After Donald Trump won all five primaries last night, he launched into an absurd diatribe against Hillary: "If Hillary Clinton were a man, I don't think she'd get 5 percent of the vote … The only thing she's got going is the woman's card." Hillary Clinton has won more than 12 million votes–that's 2 million more than Trump–because she has the best vision for this country, the chops to get the job done, and an incredible team fighting alongside her. But Trump's unpredictable, often dangerous rhetoric has created a volatile atmosphere in this race that requires us to be even more prepared than before. This campaign is going to need deep resources for the wild ride that likely awaits us. If you’re ready to fight by Hillary’s side, chip in right now (when you do, we’ll send you a free sticker).

Clinton all but locked up the Democratic nomination Tuesday night with four victories in five states, widening her pledged delegate lead over Sen. Bernie Sanders (I., Vt.) in the Democratic primary. Clinton also holds a large lead with "superdelegates" over Sanders, who appeared to signal Tuesday night that any path to victory for him was essentially gone.

Trump swept all five states in the Republican primary contests Tuesday to increase his lead in the delegate count over Sen. Ted Cruz (R., Texas) and Ohio Gov. John Kasich. He is trying to reach 1,237 delegates to avoid a contested GOP convention.
