Markey: Has called his vote for President Barack Obama's 2010 federal health care overhaul the proudest of his congressional career.

INTERNET SALES TAX
Gomez: Opposes federal law to apply sales tax to purchases on the Internet, saying it would raise costs for consumers and impose burdensome regulation on businesses.

HOME MORTGAGE DEDUCTION
Gomez: Does not rule elimination of the home mortgage interest deduction as part of a comprehensive federal budget deal, though adds it would be at the bottom of his list of potential actions.
Markey: Has said home mortgage interest deduction should be off the table in congressional budget negotiations.
MEDICAL DEVICE TAX
Gomez: Supports immediate repeal of tax on medical device companies that was part of federal health care overhaul, saying it hurts key industry in Massachusetts.

Markey: Supports use of armed drones overseas in limited circumstances when national interests are at stake. Believes any use of domestic drones should be accompanied by strict rules against spying on Americans.
Gomez: Believes former intelligence contractor Edward Snowden, who claimed responsibility for revealing NSA surveillance programs, should be prosecuted. Also says there is a fine line between national security and personal privacy and that NSA may have gone too far absent an imminent threat to national security.
