Five Senate Republicans have joined all but one Democrat in saying they will vote to confirm Supreme Court nominee Elena Kagan.

At least 51 senators have announced they will back Kagan, who's expected to be confirmed by the end of the week.

GOP Sens. Lindsey Graham, Susan Collins, Olympia Snowe, Judd Gregg, and Richard Lugar have all openly said they will be among those in favor of her.

CBN News spoke with Andrea Lafferty, executive director of the Traditional Values Coalition about Kagan's past and whether she could be a good, impartial Supreme Court justice.

Still, most of their Republican colleagues argue that the former Harvard Law School dean isn't fit to be a justice because she's let her liberal political views guide her decisions in the past.

"I'm very serious when I say that the actions of this nominee over the period of her career indicate an approach to judging that is inconsistent with the classical American view of a judge," Sen. Jeff Sessions, R-Ala., said.

"As one who shows restraint, who follows the law, who adjudicates the matters before the court and who is objective and fair."

Last week, Sen. Ben Nelson, D-Neb., became the first Democrat to oppose Kagan's nomination. Nelson joined Republicans in criticizing Kagan's lack of judicial experience.

"[I] have heard concerns from Nebraskans regarding Ms. Kagan, and her lack of a judicial record makes it difficult for me to discount the concerns raised by Nebraskans, or to reach a level of comfort that these concerns are unfounded," Nelson said.

If confirmed, Kagan will be the fourth woman in history to join the court.
