As voters from two more states head to the polls this Tuesday, Democratic frontrunner Hillary Clinton won't be making a peep.

The expected Democratic nominee has no public events today and press has not been advised of any campaign events tomorrow.

She'll be laying low as she's likely to get walloped by rival Bernie Sanders in Oregon, while Kentucky voters could hand Clinton another loss as well, as the former secretary of state hobbles her way through the end of the Democratic primary calendar.

Hillary Clinton decided to play ball in Kentucky, with her campaign running television and radio ads in the state, and the candidate personally visiting three times - but she won't be speaking from there tonight

After a string of wins under a month ago – in Pennsylvania, Delaware, Maryland and Connecticut – that allowed Clinton to pivot toward the general election, voters in Indiana, and then in West Virginia, essentially told the frontrunner not-so-fast, with Sanders snagging the majority of pledged delegates in both contests.

This led to a recalibration within the Clinton campaign, which initially wasn't going to spend any more money on the primary elections.

Instead, her campaign paid for radio and television ads to run in the state's major markets.

They dispatched more than a dozen surrogates to the Bluegrass State, according to CNN.

And Clinton personally visited the state three times, making 11 campaign stops in an attempt to sway voters her way.

Kentucky holds a closed primary, which could help Clinton, as independents allowed to vote in the Democratic primaries have heavily favored Sanders.

There's been limited polling in the state, but the last poll, conducted in early March, had Clinton up five points too.

That being said, she could also experience a repeat of what happened in West Virginia where comments she made about putting the coal industry out of business – along with the miners too – had gone viral, killing her chances with Democratic voters who were connected with the industry.

Instead, Hillary Clinton is laying low this election day as she hobbles closer to the Democratic nomination, which she's still expected to win despite Bernie Sanders' late stage wins

Sen. Bernie Sanders has said he plans to stay in the race, spending yesterday in Puerto Rico, where voters don't head to the polls until June 5

While Kentucky's coal industry is not nearly as big as the one in West Virginia, it's still an important piece of the state's economy.

The perception that Clinton was anti-coal handed her a loss in West Virginia of 51.4 to 35.8 percent.

Meanwhile, in tonight's other primary – Oregon – Sanders is expected to have an easy win, though the little polling that was conducted in the state had Clinton ahead.

Nate Silver's model at 538.com gives Sanders a 15-point advantage, which is less than the about 45 point win he received next door in Washington State, because Oregon holds a primary, not a caucus and only Democrats can participate.

The Democratic electorate in Oregon is whiter than that of Kentucky, which gives Sanders an edge in the Western state too.

Moving beyond tonight, Sanders has no intention of throwing in the towel, even though these late stage wins won't really change the delegate math.

After spending time in Kentucky over the weekend, Sanders spent his Monday in Puerto Rico on a whirlwind island tour.

Puerto Rico has the most pledged delegates still on the table after California, the biggest delegate prize, and New Jersey, which comes in second.
