(CNSNews.com) -- After Sen. Jeff Flake (R-Ariz.) gave a speech on the Senate floor Tuesday to announce he would not run for reelection in 2018 and to harshly denounce President Donald Trump--"reckless, outrageous and undignified...dangerous to a democracy"--many conservatives denounced his remarks and noted that he apparently did nothing to advance the cause of liberty while in office.

On his popular talk-radio show, best selling author and attorney Mark Levin said, "Tell me one thing Jeff Flake did to help restore this Republic, just one thing. Tell me. He voted for Gorsuch? There would be no Gorsuch but for the fact that Trump nominated him. And they go to the floor and make these speeches like they’re Daniel Webster. They’re no Daniel Webster. They’re a joke!"

Best selling author and columnist Ben Shapiro in several tweets said, "Flake blaming his fall on Trump and the supposed inability of the base to support good people is disingenuous and cynical. Flake was deeply unpopular for years and was going to lose. Not because of Trump. Because he broke faith with his base. Blaming Trump and Trump voters is a way of playing hero while quitting because he was going to lose."

David Bozell, president of ForAmerica, said in a statement: "Make no mistake: Jeff Flake is leaving the Senate because he doesn't fight for the conservative agenda mandated by his constituency and therefore he cannot win reelection."

"Jeff Flake is a con and a liar," said Bozell. "He is a look-at-me non-leader who ripped off Barry Goldwater's book title Conscience of a Conservative."

"As evidenced by his Senate floor speech today, Flake spends more time and energy criticizing the president's tweets than he does fighting against liberals in the U.S. Senate," said the ForAmerica president.

In response to Sen. Flake tweeting that he gets goosebumps when at the Capitol, conservative Mark J. Fitzgibbons, president of American Target Advertising, tweeted, "We get goosebumps that you're leaving, Sen. Flake. You let conservatives down. And don't leave mad, just leave."

Talk-radio and television host Sean Hannity said Flake is not running for reelection because polls in August showed he had an 18% approval rating among voters in his own state. Also, Republican challenger Kelli Ward, a conservative, is polling very well in Arizona. Analysts predict Flake would lose in the primary to Ward.

Commenting further, Hannity said Flake and Sen. Bob Corker (R-Tenn.), who also is not running for reelection, need to leave Congress because they have not kept their promises to voters and do not support a conservative agenda.

“These guys have accomplished nothing, and others like Ben Sasse too," said Hannity. "Good riddance. Happy trails. Don’t let the door hit you on the way out.”

“Take your other colleagues with you," said Hannity. "Mitch McConnell, goodbye! Ben Sasse, goodbye! John Cornyn, goodbye!"

Conservative Erick Erickson tweeted, "Jeff Flake is No Martyr. Steve Bannon Did Not Defeat Him. And the Media is Full of Crap on This Story."

An adviser for Steve Bannon's PAC, Great America Alliance, Andy Aurabian, told the Washington Post, "This is a victory for President Trump and all of his supporters across the nation. Jeff Flake was America’s top ‘Never Trumper,’ so getting his scalp is a signal to Never Trumpers everywhere that their time is up.”

"The days of establishment Republicans who oppose the people's America First agenda are numbered," Steve Bannon told The Post. “Many more to come.”

Conservative leader Brent Bozell tweeted, "Flake can blame Trump all day long. The truth is, his voters wanted him thrown out. He was a disgrace."

Commenting further on the issue in general, Mark Levin said, "Donald Trump may not be a constitutional conservative, but he is doing many conservative things, unlike the United States Senate. The advances we have made so far, such as they are, in dealing with the progressive state have come from the Trump presidency. … Very little if anything has come from the Republican-controlled Senate and Republican-controlled House."

As for Sen. Corker, Levin added, "Bob Corker is a deceitful, thin-skinned fraud. He’s an ego-maniac. And if you think Trump’s tweets are bad, Corker’s tweets are repulsive. As a matter of fact, Corker is repulsive because he’s now going where nobody goes: insisting that the president of the United Sattes is mentally unfit to be president of the United States. Have you ever heard a senator, in the same party, say such a thing? Which he knows not to be true?"

"Bob Corker is a fraud, he’s a coward," said Levin, who heads the fourth most popular talk-radio show in the nation. "He runs to the liberal media, he gives them what they want. He burps out these outrageous comments and the liberal media repeat them."
