New tone.

(Orlando Sentinel) — Vice President Joe Biden turned a dinner speech to Florida Democrats at Walt Disney World into a pep rally Friday night, blasting Republicans as obstructionists with whom he said the administration can no longer work.

Biden knocked Republicans for blocking President Obama’s American Jobs Act, for “playing roulette” with the federal deficit ceiling and standing in the way of other Obama initiatives, from Wall Street reform to health-care reform to the end of the Iraq occupation.

Biden said he and Obama tried for 2½ years to sit down with Republicans and now he concludes, “This is not your father’s Republican Party.”

“It’s time to stand up. It’s time to fight back,” Biden bellowed to a cheering crowd of more than 1,000 people at the Florida Democratic Party annual convention at Disney’s Contemporary Resort. “We are looking for this fight.”

Paraphrasing President Franklin Roosevelt’s attacks on his Republican critics in the 1930s, Biden belittled House Speaker John Boehner, House Minority Leader Eric Cantor and Senate President Mitch McConnell as “a beautiful rhythm of obstructionists, Boehner, Cantor and Mitch.”

Biden accused Republicans of creating the very budget deficits that they campaign against, and of not understanding that their tax-cuts proposals and vow to kill health-care reform would make the budget situation worse.
