GOP presidential hopeful Marco Rubio hit the hustings in New Hampshire and blasted likely Democratic nominee Hillary Clinton as the darling of Wall Street, saying she’ll raise record sums from big bankers and side with them over Main Street America.

“Ultimately, look, if Hillary Clinton runs for president, she will get more money out of Wall Street than any presidential campaign ever — and that’s a fact,” Rubio said at Lawrence Barn Community Center in Hollis, N.H., yesterday. “Part of the reason is that many of these industries feel very comfortable with her there.”

The Florida senator said Wall Street big shots believe Clinton will back monetary policies “benefitting them at the expense of a retired couple that’s saving money … or a small business that’s trying to take out a loan at a traditional bank.”

But asked by a Herald reporter how a possible Democratic primary challenge by Massachusetts Sen. Elizabeth Warren — who has repeatedly slammed Wall Street’s influence in politics — might affect a Clinton 2016 campaign, Rubio wouldn’t say: “Oh, I don’t know guys, I’m not a Democratic prognosticator. I’ll let that work itself out.”

Rubio also sought to link Clinton to President Obama’s failures on the economy, arguing single women and minorities would fare the worst under her administration.

“They’ve been hurt most by this economic lack of recovery that we face as a nation, and she’s for continuing the same policies,” said Rubio. “She has yet to distinguish herself in terms of what she would do differently than Obama would.”

Rubio is on a two-day sweep through the notoriously unpredictable first-in-the-nation primary state, hitting a question-and-answer session in Hollis before signing copies of his book “American Dreams” at a Barnes & Noble in Manchester. He’s also slated to speak this morning at a “Politics & Eggs” event at St. Anselm College.

Rubio said he’s wrestling with whether he’d be more effective in the White House or in a Republican-controlled Senate.

If he runs, he’ll be taking on his former mentor, ex-Florida Gov. Jeb Bush, whose campaign is expected to be a fundraising dynamo. But Rubio signaled he was serious about a possible White House bid last week when he reportedly hired Granite State operative Jim Merrill as a senior adviser.

Rubio said yesterday he’ll decide this spring, and brushed off suggestions his flirtation is merely a publicity stunt to flog his book.

“Well, look, obviously I want people to get my book and it’s not just because we published it, but because we want them to read the ideas,” he said. “At the appropriate time near — very soon — we’ll have to make a decision about where the best place is for me to serve this country.”
