Asian shares fell on Tuesday amid uncertainty about Senate runoffs in Georgia, which could have a big impact on incoming US President Joe Biden's economic policies.

In the United States, control of the Senate is at stake with Tuesday's dual runoff elections in Georgia.
A Democratic victory in both races could tip control of the Senate away from Republicans, but both contests are very tight and the results may not be immediately known, which could lead to a repeat of the chaotic vote re-counts after the US presidential election last year.
"2021 starts with a bang with pivotal political and economic news for markets to digest. The undisputed highlight will be the result of the Senate seat run-off elections in Georgia," James Knightley, chief international economist at ING, wrote in a research memo.
"If the Democrats win both seats this should lead to the most substantial 2021 fiscal stimulus. Nonetheless, it could be the excuse for a near-term consolidation in risk markets after a strong post-election rally."
Uncertainty about the Georgia vote and worries about rising coronavirus infections sent Wall Street sharply lower on Monday.

Outgoing Republican President Donald Trump's call to pressure Georgia's top election official to "find" votes to overturn his loss to President-elect Biden in the state as also unnerved some investors.
The House and the Senate are scheduled to certify Biden's election win on Wednesday, but some Republicans have pledged to vote against this and thousands of Trump supporters are expected to converge on the capital in protest.
