Democratic and Republican candidates were still trying to win over undecided Americans on Monday, with a week to go before the midterm elections. Both sides know these votes are typically approached as referendums on the party in power.

Analysts with the political news site and polling aggregator RealClearPolitics say the Democrats are likely to lose their majority in the House of Representatives. The polls suggest the battle for the Senate remains tight.

Former President Donald Trump has endorsed more than 200 candidates. They and other Republicans blame President Joe Biden for the high prices of goods and services. They are also tapping into Americans' fears about crime.

Democrats have encouraged people to take advantage of early voting. Biden is among the millions who have already cast their ballots.

The President has seen his support fall over the past few months. The analysts at RealClearPolitics put his job approval rating at 42.7 percent. He is keeping a low profile in the race.

Former President Barack Obama has returned to the campaign trail to try to rally his party. He has implored Democrats to "resist the temptation to give up."
