Former Vice President Joe Biden's visit to Birmingham to campaign for Doug Jones demonstrated a "sharp contrast" in the Senate race between Doug Jones and Republican Roy Moore, the Moore campaign said Tuesday.

In a statement, Moore campaign chairman Bill Armistead tied Jones to unpopular Obama administration policies, and said Jones would be a "liberal" akin to Senate Minority Leader Chuck Schumer if he's elected.

"Alabamians are opposed to the job-killing, budget-busting policies of the Obama-Biden administration that Doug Jones embraces," Armistead said in a statement. "His invitation for Joe Biden to come to Alabama to campaign for him is a clear signal that if Jones were in the Senate, he would work hand-in-glove with other liberals like Chuck Schumer and Elizabeth Warren. Replacing Senator Jeff Sessions with Doug Jones would be akin to replacing President Trump with Al Franken. Doug Jones can never fill the shoes of Jeff Sessions."

Biden, a personal friend of Jones for nearly 40 years, campaigned for the Democratic candidate in December's special election at the Birmingham-Jefferson Convention Complex before a crowd of 1,100 people. He vouched for Jones' integrity and character, and in a reference to Moore said, "We don't need another extremist in the United States Senate.

But the Moore campaign argued that Jones was on the wrong side of the issues, including abortion; Jones is pro-choice.

"Today, we are witnessing the beginning of a clear contrast between Judge Roy Moore, the conservative voice for Alabama, and Doug Jones, the liberal voice for big government," Armistead said. "Doug Jones has been trying to fool Alabama voters into thinking that he is really one of them, but he has shown his true colors by bringing in President Obama's Vice President to campaign for him and raise money for his campaign. Jones's embrace of Joe Biden reveals his true colors as a supporter of the Obama-era policies that have put the long-term safety and security of America at risk."

In response, the Jones campaign said in a statement:

"We need to start listening to each other and work together across party lines to get things done. Name calling, divisiveness and hate are not going to create jobs, fix health care or get our children a first rate education. We don't need another hyper partisan in Washington. We need a sensible voice -a Senator who will work with both sides and make Alabama proud."

Some of Jones' supporters who attended Tuesday's rally with Biden disagreed that the former vice president's appearance would backfire on the Democratic candidate.

"Doug couldn't have had a better spokesperson with him," said Ed Boutwell, a Birmingham resident and nephew of former Lieutenant Governor and Birmingham Mayor Albert Boutwell. "Mr. Biden is just about as good as you can get. He's always had a heart."
