Wall Street looked set for a higher open on Wednesday, after the Republican Party took control of the Senate and data showing the U.S. economy created 230,000 private-sector jobs in October.
The labor report from ADP and Moody's Analytics came in just above expectations of 220,000, and marked the second biggest monthly gain of the year.
The Republicans, who also added to their House majority in Tuesday's elections, will have at least 52 seats in the upper chamber, with two races as-yet undecided.
"The markets have a sense of cautious optimism," said JJ Kinahan, chief derivatives strategist for TD Ameritrade. Investors may be feeling some confidence, he said, as the new state of affairs in Washington D.C. could lead to resolutions on major political stumbling blocks.
