In another sign of how worried the GOP establishment is of Donald Trump, former presidential candidate and son and brother of former presidents Jeb Bush has endorsed the establishment's last stand against Trump: Ted Cruz. Following a semi-endorsement from Mitt Romney, who voted for Ted Cruz last night in Utah, the GOP is forcefully throwing its weight behind the Texas Senator.

Hillary Clinton and Donald Trump both picked up wins in Arizona last night, affording them the lion’s share of the night’s available delegates. Sens. Ted Cruz and Bernie Sanders did, however, add wins to their tallies, as well. Ted Cruz was able to obtain over 50% of the vote and win handily in Utah, whereas Sanders was also able to win in Utah and Idaho.

In a surprising turn in the Democratic nominating contest, former President Bill Clinton seemed to attack President Obama’s legacy. Campaigning for his wife in Washington state, Clinton said: “If you believe we can all rise together, if you believe we’ve finally come to the point where we can put the awful legacy of the last eight years behind us … then you should vote for her. She's the only person who basically had good ideas.”

The pro-Trump Great America super PAC is launching a TV ad buy in upcoming primary states totaling almost $1 million. The ads will run across the country but there will be a focus on New York, Pennsylvania, Rhode Island, Maryland and Delaware. The ad buys come at a time when the stop-Trump campaign is going on the offensive.

While defeated Florida Sen. Marco Rubio’s donors continued to pour money into his campaign last month, Texas Sen. Ted Cruz raised nearly $12 million in February. By the end of the month, he still had $8 million left to spend. Cruz also has the support of various super PACs, which have raised a total of $51 million through the end of February.

GOP front-runner Donald Trump will be in Washington, D.C. today for meetings and to make an address to the AIPAC conference. Trump will likely meet with Republican members of Congress. He has a meeting scheduled at the law firm Jones Day, where Sen. Tom Cotton is expected to be in attendance. Hillary Clinton will also address AIPAC today, several hours before Trump is slated to speak.

In a significant break from what other GOP presidential candidates have been saying, Ohio Governor John Kasich told CBS’ “Face the Nation” that Republican Senators should probably at least meet with the President’s nominee. Going further, Kasich even suggested that he might look at Garland as his own choice of nominee, should the Governor end up winning in November.

Despite calls from Democratic leaders that it is time for Sanders to start winding down his campaign, grassroots support for the Vermont Senator is not waning. At campaign stops over the weekend in Washington state, three Sanders rallies were attended by more than 30,000 people. Washington holds its primary caucuses this Saturday.

The New York Times compared total ad spend so far with the value of free media that the candidates have obtained. Trump is far and away the candidate that has spent the least, while raking in billions in free air time. According to the study, Trump has spent about $10 million on paid media, compared to an incredible $1.898 billion in earned media.

The Anonymous collective, a group of hackers, announced that it would target the “deeply disturbing” candidate Trump, and asks for help in dismantling his campaign and exposing private details. The group plans to take down one of Trump’s Chicago property sites by April 1, adding: “This is a call to arms. Shut down his websites. We need you to dismantle his campaign and sabotage his brand.”
