Washington DC - President Joe Biden travels to Florida on Tuesday, hoping his push for abortion rights will resonate in the conservative-leaning state.

Won by Donald Trump in the 2016 and 2020 presidential elections, and led by Republican Governor Ron DeSantis, the southeastern state has seemed out of reach for Democrats for nearly a decade.

But since the Supreme Court under Trump's presidency stripped the federal right to abortion, voters have rallied on the issue, even in solidly Republican states.

Trump, meanwhile, will be attending his hush money trial in New York on Tuesday, unable to leave court to campaign for his November White House comeback bid.

The stakes for Florida voters are high as the state supreme court recently upheld a ban on abortion after six weeks, set to go into effect May 1.

That ban could be overturned at the polls in November, however, when a state measure to enshrine abortion rights will also be on the ballot.

Since the Supreme Court returned abortion rights to each state to regulate, 21 states have banned or severely restricted abortion.

However, abortion rights campaigners have won every time the issue went directly to voters.

"Florida is not an easy state to win, but it is a winnable one for President Biden," campaign spokesman Julie Chavez Rodriguez said.

"Trump is hoping that Americans will somehow forget that he's responsible for the horror women are facing in this country every single day because of him," she added.

Biden (81) is a lifelong Catholic and has long fought Trump on abortion, an issue on which the 77-year-old has found himself pinned between hardline Republicans and more moderate voters.

Trump, who has a looser affiliation with religion, has often bragged about his role in the 2022 Supreme Court decision to overturn Roe v. Wade.

That ruling saw conservative justices he appointed help strike down a half-century of legal precedent upholding the constitutional right to abortion.

Women in Republican-controlled states have since faced problems accessing reproductive care, including for non-viable pregnancies and even IVF treatment.

And while the Supreme Court decision was a major victory for the religious right, a majority of Americans favor at least some abortion protections.

Trump has since tried to strike a more hands-off tone, suggesting at first he'd sign a 15-week ban before saying the decision belongs to the states.

Democrats aren't buying it, however, with Chavez warning, "Trump and his allies have no intention of stopping their assault on reproductive rights."

Trump's conservative vice president Mike Pence, meanwhile, wrote in the New York Times that his former boss has "betrayed the pro-life movement."

While abortion rights votes have succeeded in conservative states, it remains to be seen whether they'll translate into votes for Biden.
