What is a potential drawback to some campaign practices and tactics?
a. candidates will campaign in "battleground" states and ignore those that they think will not effect their results.
b. candidates campaign only on the radio, denying millions the chance to see them.
c. television is the primary method of educating voters, thereby denying many without television the opportunity to judge a candidate.
d. candidates only campaign through public debates in town halls and parks.

The answer is letter A.

Candidates will campaign in "battleground" states and ignore those that they think will not affect their results. Sometimes politics is all about the numbers, regardless of who they affect directly or indirectly. Political campaigns nowadays are focused on targeting individuals that belong to battleground states and they tend to forget other states that do not add to their number. In this way, people are denied their right to know about their candidates and ultimately affect their decisions on who to be voted.
