Nearly 40 percent of speeches by Senate Democrats this week were critical of vice presidential candidate Rep. Paul RyanPaul Davis RyanDon't let them fool you — Republicans love regulation, too Senate harassment bill runs into opposition from House The Hill's Morning Report — Sponsored by PhRMA — The art of walking away from the deal MORE (R-Wis.) and presidential nominee Mitt Romney.

Not counting the speeches remembering the victims of Sept. 11, 2001, 15 of 38 speeches by Democratic senators mentioned the Ryan budget.

Sen. Tom HarkinThomas (Tom) Richard HarkinDem Senator open to bid from the left in 2020 Senate GOP rejects Trump’s call to go big on gun legislation Trump should require federal contractors to follow the law MORE (D-Iowa) gave the most speeches on the budget plan from Ryan, the House Budget Committee chairman. He spoke every day on the floor, and said Romney and Ryan are keeping their real plans away from voters.

“I’m speaking to let people know what Romney and Ryan are trying to hide from them, that’s their blueprint for America,” Harkin said on the floor Thursday. “Show me your budget and I’ll show you what your priorities are.”

Republicans defended their vice presidential nominee, and said Democrats would rather criticize Ryan’s budget than work to prevent the coming "fiscal cliff" of tax increases and spending cuts that could cause a recession.

“The nation is at risk of an entirely avoidable economic calamity because the president of the United States and the Democrats who control the Senate would rather spend their time picking apart Paul Ryan and his budget plan,” Senate Minority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellGiuliani: White House wants briefing on classified meeting over Russia probe GOP senators introduce Trump's plan to claw back billion in spending The Hill's 12:30 Report — Sponsored by Delta Air Lines — Trump now says Korea summit could still happen June 12 MORE (R-Ky.) said on the floor Thursday. “It’s really a disgrace.”

Harkin said he’d continue his assault on Ryan’s budget until the Senate adjourns for the election, which is likely to happen at the end of next week. During his speeches, he argued the Ryan budget would slash funding for healthcare, Medicare, Medicaid, education, agriculture and energy, and use the money to give tax cuts to the wealthiest Americans rather than paying down the deficit.

“The Ryan budget is radical in shrinking the size of government to what it was more than a century ago,” Harkin said. “This is turning America back to where this country was before Roosevelt — not Franklin, I mean Theodore — that’s how far back this budget would take us.”

Harkin wasn’t the only Democrat speaking against Ryan and Romney.

“I rise today to talk about the so-called Ryan plan — endorsed by former Gov. Romney — which, when you read it, is nothing more than a diabolical blueprint for slashing services that help families, seniors and children all across this country,” Rockefeller said Thursday. “The Republican budget is a slap in the face to millions of Americans.”
