Fox News contributor Marc Thiessen said Friday on "America's Newsroom" that Democrats are desperate to block President Trump's eventual Supreme Court nominee, but are "powerless" to stop it. 

"[That] is why they’re having this liberal freak-out over what’s to come and they have nobody to blame but themselves," said Thiessen, a former speechwriter for President George W. Bush and a resident fellow at the American Enterprise Institute. 

Writing in the Washington Post, Thiessen explained that Democrats have no one to blame but themselves, recalling a series of missteps that brought us to the current situation, where justices can be confirmed in the Senate with a simple majority vote.

Thiessen said Democrats in 2003 took the unprecedented step of filibustering George W. Bush's appeals court nominees, including Miguel Estrada, who they were "afraid" would become the first Hispanic Supreme Court justice. 

He said the missteps continued when Barack Obama took office and Democrats invoked the nuclear option to pack the courts with liberal judges. Then last year, Senate Democrats filibustered Neil Gorsuch forcing Majority Leader Mitch McConnell to change the rules and now Trump's next pick will only require 50 votes to be confirmed. 

Trump is set to announce his Supreme Court nomination on Monday night at 9:00pm ET on Fox News Channel. The four likeliest choices are said to be appeals court judges Brett Kavanaugh, Raymond Kethledge, Amy Coney Barrett and Thomas Hardiman.
