GOP election lawyer says no evidence to support Trump's claim about mail-in voting fraud

Ginsberg, a longtime lawyer who recently retired from the practice and co-chaired the 2013 Presidential Commission on Election Administration, wrote in The Washington Post on Tuesday that Trump's recent comments about widespread fraud in mail-in voting, which risks undermining confidence in the election, and urging voters to cast their ballots twice are "doubly wrong."

"The president's actions -- urging his followers to commit an illegal act and seeking to undermine confidence in the credibility of election results -- are doubly wrong," he wrote, adding they place an obligation on Trump's campaign and the Republican Party to "reevaluate their position in the more than 40 voting cases they're involved in around the country."

He added, "Legions of Republican lawyers have searched in vain over four decades for fraudulent double voting. At long last, they have a blatant example of a major politician urging his supporters to illegally vote twice."

Ginsberg wrote, "The truth is that after decades of looking for illegal voting, there's no proof of widespread fraud," adding there are isolated incidents across both parties. "Elections are not rigged. Absentee ballots use the same process as mail-in ballots -- different states use different labels for the same process."

He also wrote that Trump's comments "make his and the Republican Party's rhetoric look less like sincere concern -- and more like transactional hypocrisy designed to provide an electoral advantage."

Last week, Trump repeatedly encouraged voters to cast their ballots twice, saying if they vote by mail they should also attempt to vote in person as a way to check if their vote is counted. Elections officials in North Carolina, Michigan and other states have warned citizens that voting twice is illegal and doing so would be met with criminal prosecution. The President has also claimed, without evidence, that voting by mail would lead to widespread voter fraud and on Tuesday encouraged his supporters to act as poll watchers to prevent fraud at voting locations.
