Biden in Florida for a final push before the midterms

US President Joe Biden rallies Democrats in Florida as he makes his closing pitch for next week's midterm elections that set the balance of power in Congress and state capitals.

As he faces signs of a growing "red wave" that could sweep the opposition Republicans to power in the House and Senate, Biden has been attempting with mixed success to court the blue-collar vote.

He travels to Hallandale Beach, a coastal city 30 kilometers north of Miami to tout his administration's progress on health care and seniors' entitlement reform.

"Millions of Americans would lose health care coverage, benefits and protections under congressional Republicans' plans," the White House said in a statement that hailed Biden-backed legislation to curb soaring prescription drug costs.

The 79-year-old Democrat had been promising since a trip was cancelled by a hurricane to go to Florida, a traditional "swing state" that has leaned more solidly into the conservative column in recent cycles.

In addition to a formal speech on health care, Biden will don his Democratic leadership hat for fundraising events for his party's gubernatorial and Senate candidates, who are both expected to lose.

The White House hopes the visit will nevertheless help in portraying the Republican Party as a threat to middle class households and seniors.

Biden has been relatively quiet during the campaign for the midterms, which are expected to hand the House of Representatives back to the Republicans.
