The United States is holding its last round of rallies nationwide as President Donald Trump steps up his campaign to rally his most fervent supporters ahead of the elections so that Democrats do not take control of Congress.

The 80-year-old president also had virtual rallies mooted instead of appearances in Iowa and Kansas this weekend after nearly a month of campaigning in Republican states. But he changed his mind later and proceeded to hold events in person on Sunday.

Trump has been on the road more than ever before on his campaign, and he told rally attendees in Dubuque, Iowa, that his reason for doing so: to block the rise of “America hating communists and jihadists” in Congress.

Republicans Face Tough Electoral Battle

The Democrats, according to opinion polls, have good hopes of taking control of the House of Representatives with the three seats they need. But Democrats are also far more confident in the prospects of their victory in the Senate where seven seats remain undecided.

But the Republican campaign’s plan to contest the Senate contest remains up to the job, with several battleground seats in the state running from Maine to Iowa, Kansas and Nebraska in sight for the party.

Questions Over Trump’s Campaign Impact

Nobody knows how effectively Trump’s rallies are working for Republicans or if it’s working for them at all. His rise to power has placed difficulties in the party’s path due to his low ratings and citizen unhappiness about the cost of living and management of foreign wars.

Trump’s more recent outings have also been noted for odd little tidbits he drops in, such as male candidates’ bodies. Democrats have taken these occasions to complain about a lack of seriousness by the president on economic issues.
