Washington (CNN) As voters go to the polls in Super Tuesday states, about 20% of Republicans say they made up their minds in the last few days, according to exit polls.

The states where GOP voters made their decisions late came in Alabama Oklahoma and Vermont

Angry Republicans turned out to vote in the South -- Georgia, Arkansas Tennessee , and Texas -- while Republicans farther north said they were not as upset with the government, but still dissatisfied, according to those early exit polls.

Meanwhile, large numbers of Republicans across the board said they felt "betrayed" by their party, with almost 6 in 10 feeling that way in Georgia and Alabama, and roughly half of Virginia Republicans feeling that way.

Republicans in Texas, Georgia and Virginia also largely said that Donald Trump ran the most unfair campaign. But Ted Cruz was also seen as running an unfair campaign by more than 2 in 10 voters in each state.

In Vermont, meanwhile, Donald Trump was facing a surprisingly strong challenge from Ohio Gov. John Kasich, who was winning strong support among independents voting there. The two split the support of Republican voters who said they were looking for a candidate who could bring change.

On the other side of the aisle, Democratic voters largely said they would be happy with either Hillary Clinton or Bernie Sanders as their nominee.

Democratic voters were also less likely than their Republican counterparts to say their candidates' attacks were unfair. Democratic voters largely decided that Sanders was not too liberal for them, nor was Clinton not liberal enough.

Clinton was projected to win Georgia on Tuesday night with strong support from black voters, who made up almost half of the electorate there, beating Sanders by more than 4 to 1.

Sanders, meanwhile, won almost unanimous support in his home state of Vermont among voters looking for a candidate who would carry on more liberal policies and a candidate who is honest and trustworthy.

On the Republican side, voters in all but Texas and Vermont said they were mostly looking for an outsider candidate.

Among Democrats, the voters were almost all white in Massachusetts and Vermont, a majority black in Alabama and Georgia and more than one-third Hispanic in Texas.

The exit polls were conducted as voters left the polls Tuesday and some trends could change slightly as more information is collected.
