It’s just one of the ways the Trump campaign is pushing voters to cast mail-in ballots. It has been targeting counties in battleground states where absentee ballots made a difference in 2016, urging supporters through a website to request ballots and running Facebook ads that state "Absentee ballots are GOOD. I need you to get your application and send in your absentee ballot IMMEDIATELY." President Donald Trump even requested an absentee ballot himself to vote in Florida's recent primary.

Trump’s assault on mail-in voting began in the spring, when he started warning there would be massive voter fraud if much of the country voted remotely, despite no evidence to back up the claims. The Republican Party and the Trump campaign have since filed lawsuits to restrict mail-in-voting measures in numerous states. Trump occasionally tries to distinguish between mail-in ballots and absentee ballots, saying the latter have additional safeguards and go only to those who request them. But election officials say the ballots look identical. Some states even use the names interchangeably or use a single term for all mail-in ballots.

A spokeswoman for the RNC, which paid for the calls, said the calls are "completely in-line" with Trump's message. “The RNC has and will continue to encourage voters to vote through the proper absentee process ‘safely and securely’ as the calls suggest, but we continue to stand against Democrats’ attempt to overhaul our elections systems and implement widespread vote by mail with no safeguards," said Mandi Merritt, the RNC‘s national press secretary.

The Trump campaign didn’t respond to requests for comment. But last week, a Trump campaign spokeswoman, Thea McDonald, blamed Democrats and the media for failing to distinguish between universal mail-in voting systems and traditional absentee vote-by-mail systems.

The Trump campaign is targeting 17 states this November. Robocalls are not allowed in two of them — Minnesota and New Hampshire. The last state, Nevada, recently decided to send ballots to all voters, which Trump opposes.

It's expected that tens of millions of Americans will cast their ballot for president by mail this year — many in Republican-dominated states and swing states where Republican turnout is crucial for Trump — amid the coronavirus pandemic.

More than two dozen states, run by Democrats and Republicans, have already made voting changes to facilitate mail-in voting ahead of November’s election. In the past, researchers have found universal mail-in voting doesn’t privilege Republicans or Democrats, and election officials say it’s unclear whether either party might benefit in 2020.

Trump’s campaign and the RNC have already taken to the courts dozens of times as part of a $20 million effort to challenge voting rules, even filing lawsuits in several states where the robocalls are being made, including Pennsylvania, Virginia and Wisconsin.

Some Republicans worry Trump's escalating accusations of fraud could scare reliable supporters from voting remotely. Polling has fueled these concerns, and Democrats are outpacing Republican requests for absentee ballots in some swing states.

Several speakers at the convention this week have tried to ease concerns about mail-in voting. RNC Chairwoman Ronna McDaniel urged voters to text if they wanted to "check your voting status, secure your ballot, or register to vote."
