(CNN) - As the Senate prepares to vote on President Obama's jobs bill, the Obama campaign released a memo by senior strategist David Axelrod that seems designed to give wavering senators reason to vote for the bill: it makes the case that "there is no Republican alternative that would create jobs now."
The memo, filled with polling data, says "the American people have rallied around Obama's call to pass this plan" and that "after 3 weeks of advocacy by the President, support (for the jobs bill) has grown by nearly 10%."
Axelrod also takes on the Republican charge that the president is engaging in class warfare, writing that a majority of Americans support the Democrats’ millionaire’s tax - increased income taxes on people who earn a $1 million or more a year.
"While Republicans may claim that this is class warfare, the American people are seeing right through their opposition to asking the wealthiest to do their part," the memo says.
Axelrod cites data that show that independents increasingly trust the president more than they do the Republicans to create jobs.
In the end, the memo is unlikely to change Republicans minds. But a number of Democratic senators have expressed uncertainty about the bill, including moderate Democrats and those facing tough re-election fights.
The jobs bill the Senate will vote on Tuesday evening is not expected to get the 60 votes needed to clear a procedural hurdle, which means the Senate would not formally take up the bill.
